Core: Partial revert of rcb3188281e, rc85b35f076, r97f9a0fa3e due to missing loader implementation.

(files disabled but kept in repo, and will be fully reinstated once everything is sorted out)
Note: SQL-update-data is NOT supplied for 're-converting' to old help-system - this is after all considered a workrepo untill we tag a commit as stable!
